NHTSA Complaint #11033424 — 2013 KIA OPTIMA

THE ANTI-LOCK BRAKING SYSTEM FAILED ON THIS CAR. IF YOU WOULD HIT A BUMP IN THE ROAD WHILE ACCELERATION THE CAR WOULD DETECT A SPINNING CONDITION AND CAUSE MAJOR DECELERATION BEING VERY DANGEROUS WHEN ENTERING A FREEWAY IN MODERATE TRAFFIC TAKING THE VEHICLE FROM 60+ MPH TO VIRTUALLY 40 MPH WITH NO WARNING AND NO BRAKE LIGHTING TO WARN APPROACHING TRAFFIC. AFTER MANY VISITS TO KIA DEALER REMAINED UNADDRESSED UNTIL CONTACTING CORPORATE KIA AND FINDING A POSTING ON KIA OPTIMA FORUM WITH ANOTHER USER THAT HAD SAME ISSUE AND WAS FINALLY RESOLVED WITH SOME HYDRAULIC PART REPLACEMENT THAT COSTS $1,600 AND WAS BEING AVOIDED BY DEALERS. WHEN I BROUGHT THIS TO KIA CORPORATES ATTENTION THEY AGREED TO REPLACE WITH THAT PART WHICH DID ALMOST RESOLVE THAT ISSUE EXCEPT ON RARE INSTANCES CAR WILL STILL HESITATE WHEN ENCOUNTERING A BUMP ON ACCELERATION. AFTER THAT REPAIR HOWEVER THE ANTI-LOCK BRAKES ARE NOW FAILING WITH ERRATIC PULSING ON HARD BRAKING AND LESS EFFECTIVE BRAKING.
